Frequently Asked Questions (FAQ)
-
Q: What materials can be used with this mold?
A: This mold is designed for thermoplastics commonly used in cap manufacturing, such as PP, HDPE, LDPE, and PET. The cavity steel can be customized for special materials like ABS or nylon upon request. -
Q: What is the minimum order quantity (MOQ) for this mold?
A: We accept single-cavity prototype molds as well as multi-cavity production molds. The MOQ depends on the cavity count and complexity; typically, we start at 1 set. Please contact us with your specific requirements. -
Q: Does the mold come with a warranty?
A: Yes, we offer a standard 12-month warranty covering manufacturing defects. Extended warranty and maintenance services are available as an option. -
Q: Can you replicate an existing cap design?
A: Absolutely. We provide reverse engineering services. You can send us a sample cap, and we will create a 3D model and mold accordingly. CMM inspection ensures the replica matches the original within tight tolerances. -
Q: How long will the mold last?
A: With proper maintenance, the expected mold life is between 500,000 and 2,000,000 shots, depending on the material and operating conditions. Harder steel and better cooling can extend the life further. -
Q: Do you provide samples before mass production?
A: Yes, we offer sample shots (T1/T2) for customer approval. We also provide dimensional reports and CMM data for your verification. -
Q: What is the typical delivery time?
A: Standard delivery time is 30–45 working days for a simple single-cavity mold, and 45–60 working days for multi-cavity or complex molds. Rush orders can be arranged at an additional cost. -
Q: How do you ensure the mold fits my injection molding machine?
A: We require the machine specifications (platen size, tie-bar spacing, nozzle type, etc.) during the design phase. Our mold base is customized to match your machine, ensuring quick installation and no modifications.
